1 Stop Prep & Fulfillment

Founded in 2018 by Amazon sellers who were fed up with existing 3PLs, 1 Stop Prep & Fulfillment now says it serves more than 2,800 sellers across Amazon, DTC, and marketplace channels from its Nashua, New Hampshire warehouse at 1 Chestnut St, Suite 5-E. The channel list is unusually broad for a prep center, spanning Amazon FBA and FBM, Walmart, eBay, TikTok Shop, Shopify, and wholesale B2B, which makes it a fit for sellers running several storefronts at once. It reports a 99.2% order accuracy rate tracked across channels and has processed more than 1,200 returns through a graded recovery program. Services include FBA prep and compliance, kitting and bundling, returns recovery, a same-day dispatch option, and oversized handling. There are no setup fees, though most brand partners ship 300-plus orders a month, so it leans toward higher-volume operators. Google rating: 4.7 across 46 reviews.
